Inventor: HIWADA SHIGERU
IPC: B21D22/30
Filed: 1982-04-19
Abstract: PURPOSE:To secure the finish accuracy, and to prevent seizure, etc. to a working tool, by forming a ring-like recessed part on the inside wall face of the cylindrical drum part of the bottomed cylinder made of a thin plate, in the press pre-process, and absorbing the surplus thickness by this recessed part in the finish process. CONSTITUTION:A thin plate 10 is worked to cap-like forming parts 11, 12, ring- like dead thin parts 13, 14 are worked by press metallic die punches 15, 16, and a ring-like recessed part 7 is formed on a side wall 17 of a bearing part 8 by forming of the following working process. Subsequently, a squeezing punch 20 is made larger than the inside diameter of the bearing part, and when size 21 is being worked, surplus thickness being thicker than the initial set thickness is absorbed by the first ring-like recessed part 7, and in the same way, size 22 is also absorbed by the second ring-like recessed part 23. In this way, the finish accuracy can be secured by press-working without being influenced by variations of thickness and ductility of a thin plate base material, by absorving the surplus thickness by the ring-like recessed part of the cylindrical drum part.

Abstract: PURPOSE:To avert zero point fluctuations and obtain accurate measured values by performing the specific operations by the use of the respective outputs by the light having transmitted through the object to be analyzed and the light which does not transmit through the same in the infrared ray analysis method using a wavelength variable type infrared ray laser as its light source. CONSTITUTION:Light from a wavelength variable semiconductor laser 1 is passed in the atmosphere 4 containing the gas to be measured by optical systems 2, 3, 5, 6 and the outputs thereof are detected with a first detector 7. On the other hand, a part of light (light which does not pass 4) drawn out in an optical branching device 9 is detected with a second detector 10. Next, the outputs of the first detector is operated by using a pair of phase restraining amplifiers 11, 12 and a divider 13 to obtain Pr'/Pr (the value standardized by dividing the differential coefficient Pr' for the laser light vibration number of the power having passed through the object to be examined by a primitive function Pr). On the other hand, P0'/P (the value standardizing the differential coefficient P0' of the power of the light which does not pass through the object to be examined) is obtained in a similar manner and the difference between these values is obtained by way of a  differential amplifier 17, whereby the density of the gas to be measured is obtained.

Filed: 1982-04-21
Abstract: PURPOSE:To input an optional signal of 1 or 0 without using a pad which impedes high integration, by selecting a light beam irradiation position and generating the 0 or 1 signal. CONSTITUTION:An MOS type FF circuit consists of inverters 11 and 12. When the P-N junction between the drain of one MOS transistor TR16 for a driver and substrate of this FF circuit is irradiated with a laser beam, the node 18 between MOSFETs 15 and 16 is held at 0 level because of a junction current between the drain and the substrate. Consequently, the other driver MOSTR14 turns off and the nose 19 between MOSTRs 13 and 14 has a level 1. Therefore, the 1 signal appears at an output terminal 17. When the P-N junction between the drain of the TR14 and the substrate is irradiated with the laser beam, the node 19 has the 0 level. Then, the 0 signal appears at the terminal 17. Thus, the 1 or 0 signal is outputted optionally.
